Complexation between uranyl(VI) and CMPO in a hydroxyl-functionalized ionic liquid: An extraction, spectrophotography, and calorimetry study

Insights into the spontaneous multi-scale supramolecular assembly in an ionic liquid-based extraction system

“…The characteristics of the first level structure [UO 2 (CMPO) 3 ] 2+ should be clarified. 31,69 FT-IR spectra of U-MA and UO 2 (CM-PO) 3 (NO 3 ) 2 were measured, 31 in which the CQO absorption peaks of both U-MA and UO 2 (CMPO) 3 (NO 3 ) 2 split at 1613 cm À1 . For comparison, the FT-IR spectra of Al-MA, Fe-MA and CMPO are recorded in this work (see Fig.…”
